THOMAS J. PARRY, OF REMSEN, NEW YORK.

VEHIGLESHAFT.

To all whom it may concern Be it known that I, THOMAS J. PARRY, of Remsen, in the county of Oneida and State of New York, have invented certain new and useful Improvements in Vehicle- Shafts; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the reference-numerals marked thereon, which form part of this specification.

The purpose of my present invention is to provide a vehicle shaft of simple but improved construction that is easily assembled and possessed of great strength and rigidity.

A further object of my invention to to provide a shaft which is so constructed and assembled as to be especially adapted to maintain its rigidity and strength permanently and under all varying conditions of use, temperature and weather.

It is well known in the art relating to vehicle shafts that the constant jar and vibration of use tends to loosen the joints and fastening members usually used in shaft construction, and that when parts become so loosened they tend to become still looser and wear the engaging parts or surfaces so as to prevent the shaft being made as tight as formerly. Another disadvantage of shafts that may become loose is that they produce I an unpleasant amount of rattling noise;

It is the purpose of my invention to construct a vehicle shaft which shall obviate these disadvantages, and which shall be so constructed that there is no practical chance of the parts becoming loosened or making a noise. I accomplish this purpose by the special shape, arrangement and assemblage of the parts of the shaft, and particularly by so constructing it thatthe whole angle joint between the thill, crossbar and heel brace and cross piece brace are bound into one complete joint and yet in each case the metal braces are bound into contact with a wooden member of the thill, and the contact of metal braces upon other metal braces or parts is obviated. This feature particularly in conjunction with the combination of parts herein shown renders the shaft practically immune from being unfavorably affected by changes in temperature or weather, and obtains a condition most favorable for the Patented Nov. 17, 191 1.

slightly let into the top of each thill 4:, a

little forward of the heel bend 5 in the thill 4, so as to weaken the thill and cross piece as little as possible, and yet obtain an interlocking and angular bracing of the wood of the cross piece with the wood of the thill.

The heel brace 6 is formed integral with. the heel eye 7 and secured to the heel of the thill by T bolts 8, while at its forward end the heel brace has a plate portion 9 resting against the under side of the thill it and resting against thevlower side of that portion of the thill 4: against the upper side of which rests the cross piece 3, the length of said plate portion 9 being sufiicient to eX- tend slightly both forwardly and rearwardly .of said cross piece 3, as plainlvindicated in Fig. 1. A U-shaped clip bolt 10 has its strap or clip portion 11 wrapped around the exposed upper part of the cross piece 3, whilev the end of said bolts pass downward close to the sides of said cross piece through holes in the thill i and through holes in the plate portion 9 of the heel brace 6. Nuts 16 screw-threaded'on to the projecting ends of this clip bolt in an obvious manner draw the cross piece 3 down against the thill 4: and at the same time draw the plate portion 9 of said brace very tightly against the under side of the thill 4 and opposite the cross piece 3. The clip bolt 10 having its ends pass down closely at the sides of cross piece 8 through closely fitting holes in the thill f, still further prevents any motion or shifting of cross piece 3 lon- 1;. gitudinally of the thill 4C. In a similar way the projecting ends of said bolt 10, passing through similar sized holes in the plate portion 9, prevent any longitudinal motion of said plate portion 9 upon the thill.

It will be noted that the plate portion 9 of heel brace 6 engages directly againstthe bottom of thill 4 from which thill it re ceives its backward thrust and forward pull,

without the intervention of any part therebetween and particularly it will be noticed that this contact is that of metal upon wood.

The heel brace extends in a straight line from the rear end of plate portion 9 to the upper end of heel plate 17, upon the lower end of which is the heel eye 7, so that said heel brace (i is adapted to take all of the backward or forward strain Without itself bending or allowing the heel bend to be straightened upon forward strain or bent upon backward strain.

in orderto necessarily further strengthen the angle joint between the cross piece 3 and the thill l Without "weakening either the cross piece or the thill at their junction point. and without bringing such reinforcement said junction point, I provide a i brace having tail portion 13 extend-- ing along the under side of said cross piece for some distance and seeured thereto by bolts ll but not reaching to the thill l, but instead o'lf rcacl'iing to the thill l: at the junction point of said cross piece and thill the tor-lied ends 15 oi? said brace separate, a riding from both. sides oi said cross piece and are secureijl to the thill by bolts id at points on the lower side oi said thill away ilironi. the junction point oil said cross piece 3 and thill i, and also forward oi? the Forward end of the plate portion 9 and back oi the rear end of plate portion 9. it will thus be seen that this Y brace of metal cttects a strong angular reinforcement from the cross piece to the thill and is secured at all three points by contact of metal upon wood and does not rest upon or touch the heel. brace 6., its plate portion 9 nor its clip bolt 10. Also the two braces center about the same junction point and cooperate to term a stron non-rattling oint, yet do not touch each other or any part of each other and the only means connecting said braces a re the ROOfl-QD members of the shaft, mime-l5, the thill and cross piece, Which wooden members obviously transmit no sound.

the other parts. Furthermore, the fact that the two braces are separate from each other and separatel i attached to the shaft renders the operation of removing and replacing either brace simple enough for any man at all used to handling tools.

It will be Further observed that the simplicity of parts and their case of separate removal and replacement renders the repair of my vehicle sl'iat't an easy matter.

The combination. in a 'ehiclc shaft of two thills. a cross piece engaging near its ends the top ct each thill. heel braces spanning' the heel bends oi? the thill and having their rear ends secured to the rear ends of the thills and having plate portions resting against the thills beneath the cross piece, metal l ar-sterling; members engaging the top off each end oi tl e cross piece and having their ends extend through tie thills and through the plate portions of the heel lmices, means engaging said extended ends and bearing; against said heel plates and braces securet to the cross piece back from the thills and having their ends secured to the thills tircl of b races.
